ELECTROMAS'SAGE DEVICE.

SPECIFICATION forming part of Letters Patent No. 764,349, dated July 5, 1904.

Application filed March 12, 1904. Serial No. 197,766. (No model.)

To (LZZ whom it may concern.-

Be it known that I, LEE J. CHAPMAN, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Electromassage Devices, of which the following is a specification.

My invention relates to an improvement in electromassage devices.

, The object of the invention resides in providing a device comprising two dominant parts, one consisting of the cell or generating factor provided with an electrode and the other embodying the coil having a regulating and interrupting attachment and provided with an electrode, the two being connected by a twin battery-cord, the whole device be-- ing so arranged and insulated that the two parts may be grasped by the operator and applied to the affected surfaces.

Finally, the object of the invention is to provide a device that will be strong, durable, and eiiicient and one that will be convenient to manipulate and whose parts will not be liable to get out of working order.

With the above and other objects in view the invention consists of the novel details of construction and operation a preferable embodiment of which is described in the specification and illustrated in the drawings, where- Figure l is an elevation, partly in section. Fig. 2 is an elevation of the coil and its electrode, and Fig. 3 is an end view of the coil and its electrode.

The invention comprises an ordinary cell A, having the usual positive terminal B and negative terminal O, together with a coil D, having the primary coil E, a secondary coil F, and including the regulating-sleeve Or and circuit-interrupter H, the cell A and the coil D being connected by the usual twin batterycord I. The coil D is constructed with a switch J, and the cell A is suitably insulated by a proper covering. The parts above mentioned are of the usual and ordinary construction and form no part of my invention, merely being necessary accessories to a successful operation of the same.

The invention comprises, more essentially,

an electrode or shoe 1, formed of any suitable shape and conducting material, which may be fitted over the upper end of the cell A in contact with the negative terminal O, and thereby constituting the negative electrode. The coil D comprises a casing 2, of some suitable non conducting material, such as wood or hard rubber, and is formed circular in crosssection to facilitate handling of the same. The casing 2 is formed with a flat bottom 3, against which is secured the elongated rounded electrode or shoe 5 by the screws 6, thus forming an eflicient and handy device.

The parts are suitably wired, and the current passes as follows: Starting from the positive terminal B it travels over the wire 7 of the twin cord I into the casing 2 through a suitably formed opening '8, thence to the switch J and from there through the interrupter H to the wire 9 of the primary coil E. The current comes from the primary coil E, at the forward end thereof, and connected to the negative terminal C over the negative wire 10. The induced current arising in the secondary coil F passes to the electrode 1 over the negative wire 10 and through the negative terminal O. The secondary coil is connected to the screw 6 by the branch wire 11, thus conveying the current from the electrode 5 to the coil. It will thus be seen that the cell Aand the casing2 being grasped in the hands of the operator and the electrode 1 and electrode 5 being applied to the surfaces desired to be treated a direct current is established between the two electrodes and the patient receives only the induced current, the same passing through the wire 10, terminal O, and electrode 1, thenceover the treated surface to the electrode 5.

It is to be understood that the electrodes 1 and 5 may be of any suitable form in contour and that a suitable roller, brush, or other form of electrode may be employed in lieu of the form shown at 5 in the drawings. The compact and simple arrangement of the two electrodes allows the massaging of the body by moving the same with pressure over the surface thereof, allowing the current to pass through the body from one electrode to the other.

I do not wish to limit myself tothe exact deing covering, an electrode or shoe carried tails of construction and operation herein set upon one end of the cell, an insulated casing forth, as I may make various changes in the acting as a handle, means for producing a same without departing from the spirit of the variable interrupted current carried by the I5 5 invention and wholly within the scope of the casing, an electrode or shoe carried on the claims. casing, and means for electrically connecting Having now fully described my invention, the parts. what I claim, and desire to secure by Letters LEE J. CHAPMAN. Patent, is In presence of IO In an'electromassage device, a cell acting M. B. SoHLEY,
